To all whom it may concern Be it known that I, EARL Ross, a citizen ofthe United States, and a resident of Wyoming, in the county of Hamiltonand State of Ohio, whose post-ofiice address is 1.11 Springfield Pike,Wyoming, Ohio, have invented new and useful Improvements in Methods andApparatus for Ornamenting Prepared Roofing, of which the following is aspecification.

My invention relates to improvements in the method of an apparatus forthe manufacture of ornamental roofing and is.ad-

dressed particularly to ornamenting prepared flexible roofing havlng asurface layer of mineral. such as crushed slate, sand,

crushed rock and other similar mineral particles.

Prepared, flexible roofing of the type terial and then on the surface ofthat coating material place crushed slate, crushed rock, mica or similarmaterial. Such roofing has been ornamented by painting on the surface,of the exposed mineral, lines to getthe ornamental effect desired. Ihave found that by applying heat and pressure to certain portions of theroofing,'after having preheated it, that it is possible to emboss theupper surface of said roofing and make a highly satisfactory and verypleasing and economical ornamented roofing. a i In the drawings Ihaveshown longitudinal sections throughmy improved appara-' tus forornamentingroofing by my method. Preferably my method consists of takinga roll of mineral surfa'ce roofing, passing it over a preheater, steamcoils as shown in the drawing, so that the heat from the coils.

passes up through the roofing and heat same from the underside; Havingpreheated the roofing my method is to pass the preheated roofingpreferably between two rollers, one of which bears a design in reliefand which is heated so that the raised portions of said design whichcontact with the mineral surface of the roofing are heatedto the desiredtemperature. As this roofing passes between the two rolls, the heateddesign roll and the foundation roll, the raised heated portions,

formingthe design, press upon the surface of the 'mineral particles andforce same down into the coating material at the same time the coatingmaterial passes up and covers the mineral particles so that a depresslonis formed wherever the raised portion of the design rollers contact withthe roofing. Passing from the design roller" I then cool the roofing androll it up ready for a shipment. v

In the drawing, A is the roll of roofingto be ornamented, B the finishedroll. C is the v preheater or series of coils. D is an idler roll overwhich the roofing from the roll A. passes onto the preheater or steamcoils G,

E is the design roller mounted in bearings and prov1ded withmeansfor-heating the exterior of the roll and the interior. F, F

are gas mixers having burners so arranged that a flame, shown at H,contacts with the outer surface of the design roll E. G is a mixingchamber for the gas and air similar I to F, F and is provided withburnersor openings 'sothat the interior of the roll E which is-hollow isalso heated. I, I are air lines leading to the mixers F and G. H, H aregas lines leading likewise to the mixers F and G. In the gas lines atsuitable points are arranged valves J to close off they supply 1 soofgas when desired. K is a continuous belt of heavy canvas preferablywider than the width. of the roofing to be ornamented This endless beltrevolves around idlers L, L, L L L L L, L, L and L". L and L arearranged so that their positions may be' changed to' tighten or loosenthe canvas belt K. M, M are cooling drums arranged so that the endlessbelt K between the idlers L and L passes around the first cooling drumand between the idlers L and L asses around the second cooling drum.hose cooling drums are of the ordinary type and may be cooled by wateror any other suitable means. After the roofin from the roll A passesover the preheater and between the design roll E and the foun-' dat'ionor pressure roll E and has been embossed'by the design roller IE, itthen passes on the endless belt K around cooling drums M, M and isrolled up at B. N is an idler roller so arranged in relation to theidler roller L around which the endless canvas belt K passes that theroll may rest upon and be supported by the idlers N and-L I have foundthat better results are obtained by having the preheater arranged sothat it heats the roofing from the under side,

that'is, the side 0 posite the mineral surface portion and pre erably doit in this way. Of course, if desired, the heater could be above or aheater could be located both above and below.

In preheating the roofing by the apparatus .shown in the drawing I heatthe entire under i Having thusdescribed my invention what 1 I claim asnew and desire to secure by Letters Patent is:

1. In an apparatus for ornamenting roof ing of the character described,embossingmeans and means for preheating the roofing arranged ahead of,and adapted to apply heat on the opposite side of the roofing to,

said embossing means.

2. In an apparatus for ornamenting roofing of the character described,embossing means and a heating coil for preheating the roofing arrangedaheadof said embossing means. 7

3. In an apparatus for ornamenting crushed slate surface roofing, heatedembossing means and means for preheating the roofing arranged ahead ofsaid embossing" means.

4. In an apparatus for ornamenting roofing of the character described,embossing means, means for preheating the roofing arranged ahead of saidembossing means, and

cooling means for cooling the roofing arranged after said embossingmeans.

5. In an apparatus for ornamenting roofing of the character described,embossing means, means for heating said embossing means and means forpreheating the roofing arranged ahead of said embossing means.

6. In an apparatus for ornamenting roofing of the character described, aheated de-' sign roller, a foundation for supporting the roofing incontact with said design roller and means for preheating the roofingarranged ahead of said design roller.,:;

7. In an apparatus for ornamenting roofing of the character described,embossing means, means for preheating the roofing from the'under sidethereof arranged ahead of said embossing means.

8. In an apparatus for ornamenting roofing of the character described,embossing means, means for preheating the" roofing from the under sidethereof arranged ahead of said embossing means and meansz for heatingsaid embossing means.

9. The method of ornamenting aicrushed slate surface prepared roofingwhich consists in first reheating the material to which the slateadheres, then pressing a heated embossing element against the surface ofcrushed slate to embed same into the material to which it adheres andcompletely cover said slate thereby in predetermined areas.

10. The method of ornamenting crushed slate surface prepared roofingwhich consists in first heating the material to which the slate adheresby applying heat to the under side of said roofing, then pressing aheated embossing element against the crushed slat to embed-same into thematerial to which it adheres and completely cover said slate thereb inpredetermined areas.

11'. 11 an apparatus for ornamenting roofing of the character described,means forreheating the roofing and embossing means arranged after thereheating means.

In testimony whereof, I have signedmy name to this specification.
